A massage brush has a massage structure, an orientation ring engaging tightly with the massage structure, a circular pad received in the massage structure, and an exterior cover retained against the circular pad and the orientation ring. The circular pad includes a flange disposed therearround and clamps in the massage structure, and an L-shaped restriction portion extends downwardly from a bottom thereof to support the orientation ring thereon. The orientation ring engages with the massage structure, the L-shaped restriction portion, and the exterior cover simultaneously for tightly clamping the massage structure therewith.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a massage brush, and particularlyrelates to a massage brush with a tightly engaged massage structure toprevent the massage structure from being removed from the massage brush.

2. Background of the Invention

Referring to FIG. 1, a conventional massage brush 1 a includes a massagestructure 11 a, a circle pad 12 a engaged with the massage structure 11a and an exterior cover 13 a clamping the pad ring 12 a. The massagestructure 11 a has a U-shaped fastening portion 111 a made integrally inone piece and clipping a flange portion 121 a of the circle pad 12 a forthe circle pad 12 a to be received therein. The circle pad 12 a has acircular recess 122 a formed in a bottom thereof, and the exterior cover13 a has a circular protrusion 131 a arranged integrally in one piecethereon and relating to the circular recess 122 a for the circularprotrusion 131 a engaging in the circular recess 122 a. The conventionalmassage brush 1 a further includes a back paste 14 a filled between thecircular protrusion 131 a and the circular recess 122 a for a tightengagement therebetween.

However, the U-shaped fastening portion 111 a of the conventionalmassage brush 1 a becomes fatigued after long-term use and there is noretaining device or structure securing the U-shaped fastening portion111 a, so the U-shaped fastening portion 111 a will be removed easilyand the conventional massage brush 1 a will become useless.

The conventional massage brush 1 a connects the circular protrusion 131a in the circular recess 122 a via the back paste 14 a, and accordinglymatch problems must be considered between the circle pad 12 a and theback paste 14 a, or between the exterior cover 13 a and the back paste14 a (which has a material interaction therebetween). Usually, thecircle pad 12 a and the exterior cover 13 a are made of PMMA(polymethylmethacrylate) materials. The PMMA materials are usually moreexpensive than other polymers, such as PP (polypropylene), PVC(polyvinyl chloride), and the like. But these other materials cannot besubstituted for the PMMA because of the back paste 14 a and matchproblems there between, and that keeps the cost high.

In addition, the back paste 14 a filled therein may be improper andoverfilled, and the PMMA is a transparent material, so that theoverfilled back paste 14 a will be seen and negatively affect itsattractiveness to purchasers.

Furthermore, the back paste 14 a filled therein will connect the circlepad 12 a to the exterior cover 13 a so tightly that changing the massagestructure 11 a of the conventional massage brush 1 a is impossible. Whenthe massage structure 11 a wears out, the conventional massage brush 1 ais useless. If the circle pad 12 a or the exterior cover 13 a breaksfrom incorrect use, the first conventional massage brush 1 a is alsouseless.

Hence, an improvement over the prior art is required to overcome thedisadvantages thereof.

SUMMARY OF INVENTION

The primary object of the invention is therefore to specify a tightlyengaged massage brush to prevent a massage structure thereof from beingremoved therefrom. The secondary object of the invention is therefore tospecify an easily assembled and detached massage brush, the elements ofwhich can be changed.

The third object of the invention is therefore to specify a massagebrush that can be made of other polymer materials to reduce costs.

The fourth object of the invention is therefore to specify a massagebrush that omits the back paste, so that design and material matchproblems need not be considered, and the manufacturing efficiencythereof is improved.
